To all whom it may concern Be it known that I, CHARLES A. LIND- s'rnt'm a'citizen ofsthe United States, resid-. ingat No. 138 Stratford avenue, Pittsburgh,

in the county of Allegheny and State of Pennsylvania have invented certain new cation 5 My invention relates to reyices, commonly known as anti-climbers.tor-preventin cars from: climbing over each ,other 'inicollisions' Ion-similar accidents,andpai'ticnlarly to cars lot the "types equipped with vestibules and diaphragms; to which earlier devices of .thi s :SGIVICG conditions,

;-It iswell known thatin" the event'of a collision between cars or trains traveling at greatspeed, there exists a tendency of the cars-tq -mo'unt over each other which causes thei'iihea-vy underframe of'one car to shear offend destroy the relatively light posts and braces forming the superstructure or body proper of the other car, thus causing a greater amount of damage and destruction "of. the :cars, as well as frequently a greater loss of life, than would be the case if this climbing, or mounting of the cars were prevented.

Hcretofore two distinctive methods have, been proposed and used to some extent, namely, first to provide the ends of the under frames of the cars with mechanical devices arrangedtoengage the next car,but'the means used did not permit the free movement of the cars up. and down or sidewise relative to each other, and were, therefore, impracticable; and second, to provide means at the ends of the-.nnderframes so arranged that free movement was obtained, but the de vice was so arrangedthat the partsintended to interlock-and-prevent climbing of the cars did not come..mtolinterlocking position with each other untiliomd into such posiprovi-de an anti-climbing device ha'vng inarrangedthat a limited difference in hel ht facilitate interchange of cars, etc.'

tion by great force, as in a collision; but collisions have demonstrated that such devices sometimes fail to operate asintended and are, therefore, not absolutely safe.

The main object ofmy invention is therefore to provide a device which will prevent cars from climbing over each other and at the same time eliminate any objections which may exist to earlier devices' A further object of my invention is to 0 provide a device which can be readily applied to ekistingcur constructions without the necessity of making cxpensive'chan'ges thereto.

A further object of my invention is to 6-.

A further object of my invention is td-pro, ,5; vide a' device of this class having large bearing surfaces so that the faces of the in terlocking parts may be in constant contact with each other without becoming us'eless 'from rapid wear.

A further object of my invention is to provide interlocking surfaces or parts so 'arranged that the protruding or male surfaces on the end of one car may come opposite and engage with the depressed or female surfaces -on the adjacent car. no matter which end of the cars are coupled together. '96

A further obj cct of my invention is to provide interlocking parts so arranged that cars equipped with such parts can readily-be cou led to cars not so "equipped and so shown) carried by the guide bars 7 which work loosely through holes in the form members 6.

Fig. 2 shows I used, and these in actuating the combined buffer and guide member 3, serves to keep the frame plate of one car in close contact with the frame plate of the adjacent car when they are coupled together.

The above parts are not new in my inven tion, but are essential to it in some form, and are therefore described in order to make clear the operation of my invention hereinafter described.

I p View of a lo prevent the frame plate 1, of one car end plataforemcntioned springs prescribed distance I menses invention to be coupled together with the aforementioned projections in operative en gagement in the event of one or both of the cars being turned end for end, or reversed in their relative positions to each other.

parts 13 and 13 so that there is a.

vertical clearance space between the upper edge 14; of one of the projections 13, and the lower edge 15 of the projections 13 above it on the frame plate of the adjacent car, and also a vertical clearance space between the lower edge 15 of the part 13 and the hpper edge 14* of the projections 13 of the adjacent car.

Figs. 5 and 6 show a modified form 1'? of the end platform member, and combined bufier and guide member 18, in which a projecting portion 19 of the platform memher is adapted to engage with a recess 20, in the combined bufler and guide member, used on some cars, and is shown in the drawings to show the adaptation of my invention thereto.

Figs. 7, 8 and 9 show a modified form of integral.

Figs. 13, is 21112115 show still another modification of my invention, in which; in

order to facilitate removal of the frame plate 26, for renewal or repairs or other causes, splices 27 are formedbetwcen the a locomotive tender under-frame, in which 31 indicates the tender tank, 32 the sills of vthe v mderframe, and 33- the end sill, to which an end platform member 34: is socured. On. the end platform member and 5nd sill 1a frame member 35 is slidahly seated, being retained in such position by the members 36. The lower portion of the frame member 35 is provided with a combined buffer and guide portion 37, having a projecting portion 38 adapted to engage with a recess 39, formed in the end platform member 34, and operating in a manner similar to that described in connection with Figs. 1 to 4 of the drawings. The outer face of the upright portions of the frame member 35, is provided with the projections 18 and 13 suitably located and adapted to engage with the frame plate on the end of the adjacent car as hereinbefore described. While the drawings illustrating this modilication of my invention show the frame member 35 as being of limited height compared with the frame member of a. vestibule car, it is L0 be understood that it may be made of a height equal to that of the frame plate of the car,-and that the upper portionof iame member 35 may be supported against the tank by suitable devices, the same as used on the upper .end of frame plates on cars, if found desirable.

In the application of my invention it will be found necessary, to provide clearance spaces 40, shown in Figs. 1, 2, 5, 7, 10 and 13, in the end portions of the face of the combined buffer and guide members. These spaces are for the purpose of permitting the projecting portion of the face of the combined buffer and bearing member to pass the face of the projections 13* at the lower ends of the legs of the frame members, when the ends of the cars move sidewise relative to each other owing to side movement due to curvature of tracks and other causes.

The upper portion 11 of the frame plate 1 and its downwardly extending leg portion 11 are made of a thickness equal to the thickness of the frame plate plus half the thickness of the projections 13 or 13, thus insuring a substantially close contact of the portions 11 and 11 of one car with the corresponding portions 11 and 11 of the adjacent car changeable feature of my invention and also maintaining the substantially weathertight joint between the upper portions of the frame plates of adjacent cars as with and so preserving the interframe plates without my invention. The

clearance spaces between the upper and lower edges of the projections 13 and 13 are covered by the adjustable vestibule shield curtains commonly used, and which requires no particular description.

it is immaterial, in the adaptation of my invention Whether the frame plates are formed of corrugated metal, the corrugations forming projections of the desired size, or whether the projections are formed of separate pieces of metal and acuredto the frame plate, or Whether the projections are formed inte ral with the frame plate, so long as the said frame plates are provided with projections having interlocking edges and bearing faces that will prevent more than a limited amount of vertical movement with relation to each other, and so located that the parts are adapted to interlock With similar parts on adjacent cars, and so that the cars can be reversed or turned end for end and coupled together without defeating the object of my invention; and it is also immaterial What particular construction of springs is applied at the top of the frame plate, and what particular construction of combined buffer and guide member and end platform casting is used, so long as they are adapted to engage each other and prevent more than a limited movement of the end frame relative to the car, for my invention broadly consists in having opposing interlocking members projecting from adjacent cars, adapted to permit a limited vertical movement of the ends of the ears relative to each other, and a side wise movement to compensate for curvature of tracks and other causes.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is:
